Fuel Reduction, Seeding, and Vegetation in a Juniper Woodland

Creator:: Kerns, B. K. and Day, M. A.
Abstract:: Western juniper has increased in density and distribution in the interior Pacific Northwest since the late 1800s. Management goals for many juniper woodlands are now focused on reducing tree densities and promoting biodiversity, prompting the use of fuel reduction treatments. Fuel reduction often involves mechanical cutting and disturbances such as...

Dissipation-range geometry and scalar specta in sheared stratified turbulence

Creator:: Smyth, William D.
Abstract:: Direct numerical simulations of turbulence resulting from Kelvin{Helmholtz instability in stratified shear flow are used to examine the geometry of the dissipation range in a variety of flow regimes. As the buoyancy and shear Reynolds numbers that quantify the degree of isotropy in the dissipation range increase, alignment statistics evolve...

Ionic balance and organic acids in western redcedar, western hemlock, and Douglas-fir seedlings grown in low- and high-N soils

Creator:: Graff, J. E., Hermann, Richard K., and Zaerr, J. B.
Abstract:: Seedlings of western redcedar (Thuja plicata Donn ex. D. Don), western hemlock (Tsuga heterophylla (Raf.) Sarg.), and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) were transplanted into soils with low and high levels of available NO3 – (and total N). Current-year foliage was sampled after 10 weeks to determine the effect of...

Genetic variation in cold hardiness of Douglas-fir in relation to parent tree environment

Creator:: Balduman, Lisa M., Aitken, S. N., Harmon, M., and Adams, W. T.
Abstract:: The extent to which parent trees within breeding zones of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) are locally adapted to their native environments was evaluated. Forty families from each of one Coastal and one Cascade breeding population in Oregon were assessed for cold hardiness and growth phenology, and...

Structure and composition of unmanaged riparian forests in the coastal mountains of Oregon, U.S.A.

Creator:: Pabst, Robert J. and Spies, Thomas A.
Abstract:: We characterized the structure and composition of unmanaged riparian forests in three river basins in Oregon’s coastal mountains. Our objective was to evaluate stand attributes at three spatial scales: streamside (site), drainage network (stream order), and basin (subregion). Data on basal area, species composition, snag density, canopy cover, and tree...

Diversity and productivity of hypogeous fungal sporocarps in a variably thinned Douglas-fir forest

Creator:: Colgan, Wesley, Carey, Andrew B., Trappe, James M., Molina, Randy, and Thysell, David
Abstract:: Although ecosystem management techniques are designed to enhance species diversity in managed forests, no comprehensive study has been conducted to evaluate effects of such techniques on diversity and productivity of hypogeous fungi (truffles). During this study, truffles were collected in a 55- to 65-year-old Douglas-fir forest from March 1993 through...

Impact of Cultivation Legacies on Rehabilitation Seedings and Native Species Re-Establishment in Great Basin Shrublands

Creator:: Morris, L. R., Monaco, T. A., and Sheley, R. L.
Abstract:: Little is known about how cultivation legacies affect the outcome of rehabilitation seedings in the Great Basin, even though both frequently co-occur on the same lands. Similarly, there is little known about how these legacies affect native species re-establishment into these seedings. We examined these legacy effects by comparing areas...

Soil Resources Influence Vegetation and Response to Fire and Fire-Surrogate Treatments in Sagebrush-Steppe Ecosystems

Creator:: Rau, Benjamin M., Chambers, Jeanne C., Pyke, David A., Roundy, Bruce A., Schupp, Eugene W., Doescher, Paul, and Caldwell, Todd G.
Abstract:: Current paradigm suggests that spatial and temporal competition for resources limit an exotic invader, cheatgrass (Bromus tectorum L.), which once established, alters fire regimes and can result in annual grass dominance in sagebrush steppe. Prescribed fire and fire surrogate treatments (mowing, tebuthiuron, and imazapic) are used to reduce woody fuels...

Location and dynamics of the Antarctic Polar Front from satellite sea surface temperature data

Creator:: Moore, J. Keith, Abbott, Mark R., and Richman, James G.
Abstract:: The location of the Antarctic Polar Front (PF) was mapped over a 7-year period (1987-1993) within images of satellite-deprived sea surface temperature. The mean path of the PF is strongly steered by the topographic features of the Southern Ocean. The topography places vorticity constraints on the dynamics of the PF...

Short-Term Butterfly Response to Sagebrush Steppe Restoration Treatments

Creator:: McIver, James and Macke, Euell
Abstract:: As part of the Sagebrush Steppe Treatment Evaluation Project (SageSTEP), butterflies were surveyed pre-treatment and up to four years post-treatment at 16 widely distributed sagebrush steppe sites in the interior West. Butterfly populations and communities were analyzed in response to treatments (prescribed fire, mechanical, herbicide) designed to restore sagebrush steppe...
